hi guys, water parameters are good before anyone asks and my other honey and 2 dwarfs are really happy. However a honey gourami I have been worried about for some time was found lying on its side at the bottom of my tank (I thought it was dead) however it was still moving and after an hour or two it was swimming along the bottom again. However it has recently slumped on the bottom again slightly curled up, there looks to be a lump on one side of him. He is also really stressed and lost his colour completely, when it comes to feeding times, he goes to eat however he gets food in his mouth and kinda spits it out but he has done this since the day I've had him for about 4 weeks. Does anyone have any advice? These are my first fish and I don't want to lose my honey.
